BASE FOR STANDING LAMPS.

SPECIFICATION forming part of Letters Patent No. 681,217, dated August 27, 1901.

Application filed December 13,1900. Serial No, 39,726, (No model.)

i To all whom it mcty concern.-

mounted and secured separate members conl stituting the horizontal conducting-pipe and the couplings for the supply-pipe and the standard of the burner.

My invention consists in constructing the base in a single casting with a bridge spany, protuberance extending horizontally from the ning the central aperture, a'central boss extending downward therefrom, and a rib or central boss to one of the marginal flanges of the base, the horizontal rib and the central boss being cored out in casting to provide the horizontal gas way or passage and the vertical passage therefrom. The outer end of the horizontal passage is then tapped with a screwthread for the coupling of the flexible or other supply-pipe, and the upper end of the vertical passage is tapped with a screw-thread for the coupling of the hollow standard on which I the burner is mounted. In the accompanying drawings, Figure 1 is a plan or top view of a base for a standing gas-lamp, illustrating my invention. Fig. 2 is a vertical section thereof on the line 2 2, Fig. 1.

l 3 represents the body of the base, cast with the usual downwardly-projecting marginal flanges 4, forming a hollow bottom, and with a horizontal rib or protuberance 5, extending inward from one of the side flanges to the center of the base, where it merges into or takes the form of a downwardly-projecting boss 6,.and where the base is made with the usual central aperture in its top the rib is preferably extended in reduced thickness, forming a bridge 7, which divides the said central aperture into two crescent-shaped openings 8 8. These openings 8 are,however, not essential and form no necessary part of my invention.

The horizontal rib 5 and central boss 6 are cored out in casting, as shown in Fig. 2, forming a continuous passage-way 9 9 from the side flange 4 to the center of .the top of the base. An internal screw-thread 10 is tapped in the outer end of the passage-way 9 for the coupling of the supply-pipe, and an internal screw-thread 11 is tapped in the upper end of the vertical passage-way 9 in the hollow boss 6 for the coupling of the standard which carries the burner.

My invention thus provides in an integral casting a complete base for standing lamps superior in efficiency and at greatly-reduced cost as compared with lamp-bases of usual construction.

Having thus described my invention, the following is what I claim as new therein and desire to secure by Letters Patent:

A base for standing lamps consisting as herein described of an integral casting having a body with downwardly-projecting marginal flanges, a hollow horizontal rib extending from one of the side'flanges to the center, a hollow vertical boss connected therewith, forming a continuous passage-way through such horizontal rib and to the top of such hollow boss, screw-threads tapped in the outer end of the horizontal passage-way and the upper end of the vertical boss for couplings of the supply-pipe and burner-stand respectively.

Signed at New York, in the county of New York and State of New York, this 28th day of November, A. D. 1900.

WILLIAM E. HAWKINS.
